| Abstract: | The high-performance liquid chromatography(HPLC)was used for the determination of robenidine residues in chicken and rabbit tissues. The drugs were extracted from tissues with dried ethyl acetate and distilled to dry. An ultraviolet detector was used at the wavelength of 353 nm. The limit of detection was 10 ng/g. A good linear relationship (concentration versus chromatographic peak area of robenidine) was showed between 5~500 ng/mL(r=0.999 9).Recoveries of robenidine from chicken and rabbit tissues were 70%~110%. RSDs were not more than 20%. |
